A method for adding ophthalmic prescription to a heads-up display is described. The method incorporates Chiolite layers on opposing sides of a lightguide to generate an optical path from an input coupler to an output coupler. The Chiolite has an index of refraction that is less than the material forming the lightguide so that light may propagate within the lightguide under total internal reflection principles. The method further includes placement of a customized prescription lens surface on an eye-facing side of the lightguide, where one Chiolite layer is between the lightguide and the prescription.
